Sorry, I had to chuckle when I saw you include law as one of the fields where lying "won't work." For many parties, lying in court does "work" for them if they can get away with it. Recent case in point: the DEA using NSA intercepts to launch investigations, then lie in court about how these investigations originally started. [1]
